To all whom it may concern:

Be it known'that 1, DAVID E. PARKER, a citizen of the United States,residing at Niagara Falls, in the county of Niagara and State of NewYork, have invented certain new and useful Improvements in A paratus 0lowing My invention relates to an electrical furnace for preparing theroduct called oxone, wherein the peroxid orming the base .of be meltedand otherwise treated so that it may be turned out in the form of cakesready for commercial use.

Peroxids are sources of active oxygen. Oxone is a product which isformed by fusing certain peroxids, referably the peroxid of sodium,which is tlien capable ofgenerating oxygen gas in the presence of carbondioxid and moisture. While sodium peroxid in the form of powder whendissolved in water, only gives forth the oxygen in its atomic state, thefused peroxid by heat of disassociation in the instant of solutiondrives out all available oxygen. It is for the purpose of preparing thisfused peroxid of sodium, which have named oxone that I have devised theproc-' ess and apparatus herewith .described and illustrated.

The accompanyingldrawings illustrate an apparatus wherein t e powdered.peroxid is fused into cakes of oXone, in shape for immediate use and inthe drawings.

Figure 1 is a side elevation of my apparatus. Fig. 2 is a plan viewthereof. Fig. 3

V is a diametrical vertical section through the peroXid container anddistribute'r, the fusing 4 is an enlarged detail of one of the electrodesupports.

In all the drawings, like numerals desig nate like parts. i

Broadly, the process for the production of ,oxone consists in submittingpowdered peroxid of sodium to the action of an electric current of whichit forms the conduct or, raising the temperature of the peroxid. to amelting point by the passa e of current, and then pouring t e meltedmaterial into'suitable molds, where itzis rapidly. the apparatus,broadly con-' cooled; and sidered, com rises a ladle, electrodes dippinginto the lad e, a temporary removable metallic resistance between theelectrodes and an electric.

, standards of any convenient :molten material as it ,'molds.

the melted peroxid from means for pouring rocess forms the sub1ect theladle. This.

of a separate app lcatlon.

The apparatus which .I have found best adapted .to carry out my rocessconsists broadly of a ladle into whic is dipped electrodes having aconducting wire connecting them for electrically heating the p'erQ id;to the proper temperature and chilling molds into which the fusedproduct from the ladle is poured.

2 designates any suitable base on which the machine is mounted and 3,upright construction carry g at their up er ends bearings for thetrunnions of the mdlting pot or ladle. The ladle is in the form ofawater-bath; that is having double walls, formed by an outer casing 4and an inner bowl 4", and is preferably rectangular in plan. The outercasing of the ladle is provided at its ends with the braces 5, whoseends project beyond the front of the ladle and are provided with thetrunnions 5 which are sup orted on the standards fluid on which theladle turns. A forwardly projecting lever 6 is pivoted on one of thetrunnions 5, the rear end of the lever being rigidly attached-to the endof the casing preferably by attaching it to the brace 5. The object ofthe lever is to tip the ladle on its trunnion; and though theconstruction I have shorvn is convenient, I, of course, need not belimited thereto as the lever may be attached to the ladle in any otherdesired manner without departure from my invention, it being onlynecessary that the lever shall be capable of tipping the ladle andshall'be properly proportioned to that end. In order that the lever mayescape the edge of the base I have bent it outwardly beyond the saidbase, as shown clearly in Fig. 2.

The top edges of the outer casing 4 rearward y support the bowl 4: ofthe ladle. Freferably this bowl is made of oopper,-gla ss or material ofthat nature being liable to crack, and ironor steel being subject to bechemically acted upon front of the ladle is a nozzle or'lip 7 of copperwhich projects out some distance beyond the face of the ladle. Thisnozzle is preferably covered so as to prevent is poured into the haveturned flanges which center and,

In order t at the molds may be turned to bring them into exact re 'sterwith the spout umirence of the mold 7 I provide the are v with sockets21 in which avpin 21 may be inserted. A stop 22 fast on thecircumference of the table 16 is adapted to contact with the handle pin21 to' stop the rotation of the mold ring when any one of the molds isexactly beneath the spout 7.

The'operation of my invention is as follows: The current used in meltingthe peroxid. is-of either the alternating or direct variety and I use acurrent from a dynamo for that purpose. The peroxid is placed in thehopper 12 in the form of a powder the hopper eing closed in order thatthe per-, oxid maybe kept from contact with theair pot until theresistance 11 iscovered, care eing taken that the peroxid is not put inposes. The furnace is started by passing .a current of electricitythrough the electrodes ;and through the resistance 11. The

erozrid is sifted gradually into the melting too rapidly as it reducesthe current until it is melted. hen the bottom of the melting pot andthe resistance are covered with peroxid the heat generated by theelectricity passing through the resistance melts the peroxid, which thusbecomes a conductor of electricity on its own account. enough peroxid ismelted to form a bath which will carry electricity in sufficientquantities to make cxone, the resistance v11'.may

' be dispensed with, the peroxid simply being sifted in as it isneeded.The current is kept on about half an hour and the peroxid is raised to atemperature of from 710 to 718 will drop through degrees.

Peroxid begins to melt at about 700 degrees F. and when the temperatureis raised between 710 and 717 degrees the carbonic acid gas containedtherein is thrown off. From 720 to 730 degrees'the peroxid throws offits oxygen. It is'for this reason that the temperature of the peroxidshould be kept somewhere between 710 and 718 degrees and that itshouldnever be raised to such a'point that the peroxid boils. The exact heatre quired would depend upon the condition of the peroxid. If-the peroxidis soft and floury, a higher degree of heat is necessary than if theperoXid is hard.

l/Vhen the peroXid has reached the proper degree of heat and isuniformly melted so that it can flow easily, the melting'pot is thentipped by depressing the lever 6 and the molten material passes out intothe molds, as the latter are rotated. As the oXone is in contact withthe upper face of the water jacketed table, time solidify sufficientlyso that the cake the opening 16 of the table.

equals three hundred and twelve times the volume of the oXone itself. Itmay be used in medical practice, for regenerating the air in submarinevessels, or for any purpose for which oxygen itself may be used.
